One series, Piggsburg Pigs!, used Canadian voice talent rather than American voice talent like most of their shows. Ruby-Spears was also responsible for the animated sequence in the 1988 film Child's Play.

The Ruby-Spears studio was founded in 1977 as a subsidiary of Filmways Television and was sold in late 1981 to Taft Broadcasting, becoming a sister company to Hanna-Barbera Productions. In 1991, Ruby-Spears was spun off into RS Holdings while most of the original Ruby-Spears library (its pre-1991 library) was sold along with Hanna-Barbera to Turner Broadcasting System, which in turn merged with Time Warner in 1996. The Ruby-Spears studio closed down and opened back up in 1994 then closed again in 1996.[2]
